I just thought I'd see what people thought of this new system from HP - it seems as though it meets the spec for what a lot of people here want to build - a low power, low noise server for media streaming.

I'm very very tempted by this. Sticking in a 30gb SSD for a super responsive media center experience, plus a couple of hard drives, an extra 2gb stick and a discrete graphics card for tv out and HDMI etc) - It seems like the perfect system. If only HP had included HDMI out! (is there any way we can get this product suggestion over to them?)

I can't think of anything that can really compete with this in the same price range, given the low power, low noise and reasonable performance.

Wow I am liking this model a lot. I'm evaluating some replacements for my current HP EX485, which is noisy and out of warranty.

My gripes with this model are:
- VGA only. Would be nice if they threw in a couple of displayports.
- AMD: I have not been keeping up with AMD's latest, but Intel seems to always the most solid and reliable chipsets. Does AMD still have problems with SATA AHCI?
- 5.25" drive wastes space. I wish they would have a slim optical size drive opening or none at all!

Is there a spot for a 2.5" drive? It would nice to keep WHS solely on a 2.5" laptop drive/SSD.

This looks like a great niche product Oli, thanks for pointing it out... and welcome back to SPCR after your long absence.

Not sure where you see $299. All links I found show only the the base model w/ 1gb ram and 160GB Non-hot-plug LFF SATA Internal for $329. LFF is obviously some kind of drive...

It seems clear the machine could be used as a combo file server + spare or utility PC if Windows 7 was installed... one would think W7 would work, tho it's not mentioned as a supported OS; only MS server 2008 & Red Hat 5 are mentioned. There are 2 DDR3 ECC slots for up to 8GB, tho the base machine comes with just 1GB.

The absence of an OS compared to HP's WHS Atom-powered boxes makes the price analysis a bit complicated. The cheapest HP StorageWorks X310 w/ dual-core atom 1.6ghz, 1tb drive, 2gb ram, 3 open drive slots and HO's customized WHS is just $400 at Newegg right now. The MicroServer obviously has a more capable CPU, but no customized OS and less capable hardware as well.

The 21 dBA noise claim is pretty good. Seems quieter than the <30 dBA spec for their home server and storage works machines. Too bad there's no back photo. We need to get one in the lab.

EDIT -- had a look at the linked video review. Looks like it's a modified mini-DTX board. The little fan on the back looks like it could become noisy at higher load or hotter weather.

The 21 dBA noise claim is pretty good. Seems quieter than the <30 dBA spec for their home server and storage works machines.

I haven't found any specifics about what to compare their 22dB figure to but I suspect we need to compare it to the rest of the Proliant line. They claim 25dB (operating, not idle) for the next model up featuring largish fans and regular Intel processors like Clarkdales and quad-core Xeons. In that spec sheet, they tell us that's the A-weighted figure for the "bystander position" and they name-drop ISO 7779 and 9296 (no idea what it means, sorry).
Random people on the web say the Microserver is "quiet" or "very quiet" but that could be quite loud and I don't trust HP's suspiciously low numbers. Maybe if the PSU's small fan doesn't spin at 23C (that's the ambient temperature they state for the measurements on the ML110) with a <50W load...

That's interesting. Seated operater SPL is what's usually used, but maybe because it's meant to be a server...

The bystander positions shall be 1,00 m Â± 0,03 m away from the projection of the reference box on the horizontal plane 1,50 m Â± 0,03 m above the floor.

So a little over a meter distance, compared to around 0.6m for seated user:\

first impression (unmodded with factory BIOS settings): I like the overall design and the price but the unit I got is not quiet. It gets a bit louder from time to time even under a light load (as well as when swiching the server on). It's not as loud as most servers obviously but you wouldn't want to sit next to one of these. Some people wouldn't mind and there are much louder PCs out there but this is SPCR. Though the noise offends my perfectionist sensibility somewhat, I think it will be quiet enough in many cases. If one could put it somewhat out of the way and behind or under a piece of furniture without loosing too much airflow or ease of access to the front panel and its drive racks (a cool feature for such a cheap server), I think the noise would be alright for all but the most picky.At least with a light load and while the case is fairly cool, the PS is quiet. I assume it's got a small fan and it's not some hum I'm hearing when the largish system fan is disconnected. There are no fans on the CPU or the (mobile) GPU. The main fan is disappointingly noisy however. One reason is that this fan is apparently supposed to cool the drives by making air move through the front panel and along the drives. As a result, the front panel only attenuates the noise slightly. This arrangement seems this cool the drives really well (I would need to try other drives than HP's to know for sure). It's overkill if you ask me.Hopefully that fan can be tamed in software. If I experienced the lowest possible setting, the first thing to try might be an in-line fan controller (does anyone make these for 4-pins?). Replacing the fan would require a lot more work and might not be possible without voiding the warranty. I guess another option would be to install a smaller fan without removing the stock fan.

Well, there's nothing in the BIOS to control the fan as far as in can see. Maybe Speedfan can do it in Windows but the RHEL5 support is a bit of a joke. I didn't really investigate the issue in any depth but I've had to use a third-party repository to check the CPU's temperature. I'm not reading all sensors so I'm obviously not controlling the fan either.While the noise would be obnoxious if I was sitting next to the box, the cooling is more than adequate. Perhaps it's necessary with more drives but, in HP's stock configuration, the fan speed (1150 rpm) is overkill (assuming the sensors don't lie). The CPU went from reporting 38C at idle to 44C (stable after boinc-ing for hours on end) under load while the drive remained very cool. And the BIOS claims the GPU and the northbridge are hotter than the CPU but not by much. The system seems to run well in x64 mode by the way.

Has anyone heard one of these as well as an SG05? I have an SG05 as a home server at the moment and like the look of this to replace it but I certainly wouldnt want anything louder than a stock SG05

At modest load, the SG05 (assuming fan speeds are tweaked) can be considerably quieter, because the HP's fans run faster, they're not as easy to slow down, and its 40mm fan can't help making more of a tonal noise.

I also got one, because ECC memory support is simply impossible to get elsewhere in a package this small. But I must concur with HFat, this thing is ridiculously loud.

I'd ordered a Scythe S-Flex to replace the system fan, but unfortunately the system requires a fan to be installed using a 4-pin connection (I don't know if the fan must support PWM) or else it powers down in less than a minute and I don't have an appropriate converter at hand. I'll try running the Scythe fan from one of the SATA power connecters and stopping the Delta fan that shipped with the system to see if I can live with the power supply noise. Replacing the fan wasn't difficult, used the included key to remove four screws and the fan simply slides out. I haven't taken the fan cable out of the loom yet, but that shouldn't be too difficult.

I don't recall it beeping. I don't know if it's even capable of beeping.Boot something that has network services and you'll know if it works.

I'm not sure the ECC works. Memtest detects ECC support but I don't have a bad DIMM to test if it actually works and I don't know what drivers (if any) support error detection for that hardware.The drivers I got can only read the CPU's temperature by the way.

HFat, thanks for the reply. ECC is supported by the chipset, so no drivers are needed as long as you have ECC capable memory installed. I wanted to have ECC, because I will probably be running Linux or Solaris on ZFS (Solaris would require another box to take care of media playback ). ECC is strongly recommended with ZFS, so the choice was made.

I previously posted about not getting graphics out, but I realized I'd managed to unseat the graphics card, and that was why I was getting no picture out. So that's settled now. I looked around and I didn't see any speakers, so I suppose it really cannot beep for errors. They are not mentioned in the documentation anyway.

I gather it's not a mainstream server chipset. I kind of trust HP on this one... but it would be nice to know for sure.As to drivers, they're not strictly needed but the point is to get a warning when errors are detected. Basic ECC may not be enough if one of your DIMMs goes bad and starts spitting correctable errors by the hundred (better replace it).

Ah, I see what you mean regarding ECC. I suppose if a stick has gone bad, ECC won't be enough to prevent crashes, but still it would be good to be alerted if errors become frequent.

I haven't decided on an OS yet, but people have been running anything from Windows 2008R2, to Linux or Solaris/Nexenta. I'm still trying to decide if it is a keeper as a media player - it all boils down how quiet it can be.

According to that link, you still need tachyometry on pin 3 after bridging 1 and 2.

This is bad design on HP's part since I suspect the system would run fine with an external fan (or even without any fan) in an emergency. They sell this product as more reliable than a PC but force downtime on you if the fan craps out!It's still a lovely box for the money (local prices have dropped a bit). I've had no issue with mine so far apart from the lack of drivers and the noise.

HFat you are right, I'll try with a 3 pin fan and see if the server remain on.

I completely agree with you. The CPU uses an heatsink so the system should be able to work even without any fan.

My question is did vlrnmz (or anyone else) find any problem using a 3-wire fan?

I'd like to build this with a Noctua or Scythe fan that is non-PWM. Reading Mike's review, there seems no advantage with a PWM fan. My plan would be to use the HP connector and simply not have the control wire in place (Just +12, GND and Sense)Appreciate any help/advice if I'm missing something.

This was not tried but it would probably work. Just keep the wiring straight; it is a PITA. I presume you'll use a hardware voltage controller for fan speed?
